A SIMPLE MODEL TO DESCRIBE DIMPLE DYNAMICS

Se propone un modelo que permite la descripcion de la dinamica de una depresion superficial (dimple) una vez que se ha formado. Las ecuaciones de Navier-Stokes son consideradas, y dos enfoques fundamentales son utilizados para simplificar el tratamiento matematico de las ecuaciones hidrodinamicas. Se consideraron ciertas condiciones que deben cumplirse en la interfase, las cuales sirven para completar el sistema de ecuaciones diferenciales y llevan a una ecuacion de evolucion que describe la dinamica de la pelicula interfacial. A fin de resolver la ecuacion se utilizo el metodo de diferencias finitas.
